GUSTAVE O. DEGENER, OF NEVI YORK, N. Y., ASSIGNOR TO UNDERWOOD COMPUTINGMACHINE COMPANY, OF NEW YORK, N. Y., CORPORATION OF NEW YORK.

COMBINEDTYPE-WRITING AND COMPUTING MACHINE.

Application filed May 27, 1913.

To all whom it may concern:

Be it known that I, GUSTAVE O. DEGENER, a citizen of the United States,residing in New York city, in the county of Ne v York and State of NewYork, have invented certain new and useful Improvements in CombinedType-l v riting and Computing Machines, of which the following is aspecification.

This invention relates to a new and improved means for automaticallycontrolling the state of one or more computing heads as to adding,subtracting, etc., and is shown in connection with a machine of thecombined typewriting and computing type, such as that illustrated in anapplication of 'VValter lVright, No. d85,0 l6, filed March 22, 1909, nowPatent No. 1,24%,397.

In prior automatic mechanisms for controlling the character ofcomputation carried on by the computing heads, either the typewritercarriage or the computing mechanism has been burdened with thisadditional mechanism, which added to the com plexity of the mechanismand slowed up the action thereof.

It is, therefore, an object of this invention to relieve the typewritercarriage and the computing mechanism of such extra burden by providing aseparate device entirely distinct from the typewriter carriage and thecomputing mechanism, for automatically controlling the character ofaction of the computing heads.

In carrying out this object, use is made of the tabulating mechanism ofthe typewriter, so that every time a tabulating key is actuated to bringthe typewriter carriage to a new computing zone or column, a controller,shown in the form of a disk, will be given a step movement to bring intoplay one or more positioning buttons according to the number ofcomputing heads. These buttons are set to shift cooperating linkagesgreater or less amounts according to their previous positions andaccording to. the computing states desired. The linkages shift gearingto change the drive as to its direc tion or activity for both the masterwheel shaft and the assisting tens-carrying shaft of the correspondingcomputing heads.

The controller disk is provided with a power of its own and with anescapement therefor actuated by a bar universal to the tabnlating keys,so that when any "tabulat Specification of Letters Patent.

ing key is actuated, the disk will be driven a step by its own power tobring into play a new set of position-determining buttons. Thecontroller disk may be returned manually at the end of each line ofwriting, so as to reenergize its motive means and so as to bring it backto its initial starting point.

In order to obviate the possibility of the operative forgetting toreenergize the controller motive means and to return the controller diskto its starting point, a lock may be provided, which, at the end of awritten line, will come into play to preventthe actuation of thecontroller and also to prevent the actuation of the tabulatiiig keys.This lock may be adjusted to any of a plurality of positionscorresponding to the terminal of the extent of controlling actiondesired.

In case of an error, or for any other rea son, the automatic mechanismmay be op- 75" eratively disconnected and the state of the computingheads controlled manually. For this purpose, the shifter operated uponby the positioning buttons is made composite, so that the train ofconnection between the 8[. controller and the computing heads can beinterrupted at this point and the state of the computing headsdetermined by the shifting of manual levers.

Other features and advantages will hereinafter appear.

Referring'more particularly to the separate parts of this invention asembodied in the form shown in the drawings, 1 indicates numeral keys and2 character keys which ar mounted on key-levers 3, so as to depress thsame and thus rock bell cranks 4 to swing type-bars 5 up rearwardlyagainst the front side of a platen 6 mounted on a traveling carriage 7.The carrier-get? has a traveling movement under the control of anescapement indicated in general at 8, which in- .cludes a rack bar 9pivotally mounted, by

means of arms 10, on the carriage 7, and engaging a pinion 11 fixed toan escapement wheel 12. The escapement wheel 12 is con trolled in itsmovement by fixed and movable dogs 13, which in turn are actuated whenany one of the type keys is actuated, by means of a universal frame 14,which is engaged by a heel 15 on each of the typebars 5 as the latterswing upwardly to strike the platen 6.

In addition to this step-by-step movement,

the carriage 7 may be given a jump or tabulating movement. For thispurpose,

there are provided tabulating keys 16, mounted on key-levers 17, whichare pivoted intermediate their ends, and support at their rear endsplunger stops 18. When a tabulating key 16 is depressed, it raises theassociated plunger stop 18'to bring the same into the path of atabulating stop 19 adjustably mounted on a rack 20 carried by thecarriage 7.

When any one of the plunger stops 18 is raised it must release thecarriage 7 from its escapement mechanism, indicated at 8. For thispurpose, there is provided a lever 21 universal to all of the plungerstops 18 and engaging shoulders 22 provided thereon. This lever 21 whenrocked, will draw on a link 23 to rock a lever 24 carrying at itsforward end a roller 25 engaging under the rack 9, so that when any oneof the tab-- ulating keys 16 is actuated, it will raise the rack 9 outof engagement with the pinion 11, permitting the carriage 7 to travelunder the traction of a spring barrel indicated When any one of thenumeral keys 1 is actuated, in addition to printing the number by meansof the type-bars 5 swinging up to strike the work-sheet on the carriage7, it also, as will be seen by reference to Fig. 2, pulls on a hook 27to rock a bell crank 28, the latter drawing on a link 29 to rock a lever30. The lever 30 carries at one end, a plunger 31 arranged in appositionto one of a series of index pins 32 suitably mounted on an index orvaluating wheel 33. Thus when a numeral key 1 is actuated, by virtue ofthe connected linkage, it will force the associated plunger 31 againstthe apposite pin 32, setting it from a projecting position on one sideof the valuating wheel 33 to a projecting position on the far side ofthe valuating wheel There is one of these linkages and plungers for eachof the numeral keys 1, and they are each arranged in apposition to oneof the pins 32.

The plungers 31 are located in apposition to the pins 32 distant amountscorresponding to their particular numeral keys; from a'four-tooth detentwheel 34. This detent wheel 34 normally engages one of the pins 32 whichhas been previously set up to its position projecting on the far sideofthe wheel 33. The detent wheel 34 looks the valuating wheel 33 againstrotation by engagement withthis pin, and is in turn locked by anescapement wheel 35 connected there to by a shaft 36. This escapementwheel 35 normally engages one of a pair of detent dogs 37 and 38provided on a rock shaft 39. -VVhen a numeral key is actuated, thisshaft 39 is first rotated in one direction to permit a movement of oneof the teeth of the escapement wheel 35 from engagement with one of thedogs, 37, to engagement with the other of the dogs, 38. Then when thenumeral key is returned to its normal raised position, the shaft 39 isrocked in the opposite direction to permit the tooth in engagement withthe dog 38 to slip by and the next tooth on the detent 35 will then comeinto engagement with the first dog, 37, permitting a quarter rotation ofthe detent wheel 34. This is all caused by the tendency of the valuatingwheel 33 to rotate, as will be hereinafter described, which rotationtends to return the detent wheel 34 by reason of the fact that the setpin on the valuating wheel 33 tends to escape by the detent wheel 34.

To rock the shaft 39 at the actuation of any of the numeral keys 1, allof the links 29 extend through slots 40 in a collar-"plate 41, which ismounted for sliding movement against the tension of a spring42. When oneof the links 29 is drawn on by the ac tuation of its associated numeralkey 1,then' the tail end of the corresponding lever 30 will engagethecollar plate 41, to force the spring 42.

same rearwardly against the tension of the The collar plate 41cooperates with a second collar plate 43 spaced therefrom to rock alever 44 resting therebetween, at one end. The opposite end of the lever44 is connected by a link 45, to an arm 46 on the rock shaft 39.

Thus it will be seen that when a numeral key 1 is depressed to set a pin32 through the aid of the plunger 31, then the shaft 39 will be rockedin one direction, and when the numeral key 1 is returned, the shaft willbe rocked in the opposite direction permitting a quarter of a revolutionof the detent wheel 34, so that the pin in engagement therewith willescape by the same and a newly set pin will come into engagementtherewith and enable the relocking of the valuating wheel 33. The extentof movement of the valuating wheel 33 depends upon the particularnumeral key actuated. That is to say, if the 2 key were actuated, thevaluating wheel would move a distance corresponding to the distance ofthe second pin removed from the pin engaging the locking detent wheel34.

The valuating wheel 33 may be normally under a tendency to rotate in anysuitable manner, as by being provided with a shaft 47, having a gear 48meshing with'a gear 49 on a shaft 50. The shaft 50 may also be providedwith a bevel gear 51 (Fig. 1) engaged by a bevel gear 52 on a shaft 53,which in turn may be driven from a motor 54 through the intermediary ofmeshing bevel gears 55 and 56 mounted, respectively, on the motor shaftand the shaft 53. A slip clutch may be provided in this gearing, so thatwhen the valuating wheel 33 is locked against movement, the motor maycontinue to rotate without damage to the mechanism.

The purpose of this rotation of the valuating wheel 33 is to enable therunning-up of numbers digit by digit into the computing wheels of one ormore computing heads, of which two are shown at 57 and 58. For thispurpose, when the valuating wheel 33 is permitted to rotate and thebevel gear 51 is likewise rotated, this movement will be communicated,by means of a bevel gear 59 meshing with the bevel gear 51, to a shaft60, which in turn transmits it through a pair of intermeshing bevelgears 1 and 62, to a vertical shaft 63. This latter shaft is arranged todrive the master-wheel shafts, of which one is indicated at 64 in Fig.5. Th refore, each master-wheel shaft is proaided at its outer end witha bevel gear, indicated respectively in connection with the computingheads 57 and 58, at 65 and 66.

Meshing with the bevel gear 65, there is provided a pair of bevel gears67 and 68 loosely mounted on the shaft 63. Likewise meshing with thebevel gear 66, there is provided a pair of loosely-mounted bevel gears69 and 70 loose on the shaft 63. Between the pairs of bevel gears 67, 68and 69, 70, there are provided shiftable clutches 71 and 72, which arecapable of occupying any one of three positions corresponding to therotation of the gears 65 and 66 in one direction or the other, or to anon-rotation of these gears. That is to say, each of the clutches 71 and72 is provided on its top and bottom with teeth arranged to engagecorresponding teeth on the inwardly-facing sides of the paired bevelgears.

It will thus be seen that when one of the clutches 71 or 72 occupies aposition connecting one of the paired bevel gears to the shaft 63, theassociated master-wheel shaft 64 will be driven in one direction, andwhen inaposition connecting the other paired bevel gear to the shaft 63,the master-wheel shaft 64 will be driven in the opposite direction. Itwill be further seen that when the clutch occupies an intermediateposition in which neither of the paired bevel gears is connected to theshaft 63, then the associated master-wheel shaft 64 will remain dormantor silent. The master-wheel shaft 64 in each case is provided with amaster-wheel indicated at 73, which engages internallyformed teeth 74 ona computing wheel 75. This computing wheel 75 is also provided withexternal teeth 76 meshing with a gear 77 carried by a dial wheel 78,which is adapted to exhibit the numbers shown up thereon through a sightopening 79 in a computing head casing 80.

The master wheel 73 may be moved step by step through the severalcomputing wheels of both the computing heads to cor respond to thewriting of the different digits on the work-sheet located on thetypewriter carriage, by means of a lever 191, which may beintermittently connected to the carriage through the intermediary of alatch 192, which engages the different tappets or stops 19 carried bythe carriage in a manner shown and described in an application of ValterWright, No. 574,813, filed August 1, 1910, now Patent 1,244,398.

hen one of the dial wheels and its associated con'iputing wheel has madea complete revolution, that is, when the number exhibited passes from 9to 0, it is necessary to carry one to the computing wheel of next higherdenomination. F or this purpose, there is provided a tens-carryingmechanism, indicated in general at 81, which depends for its action onthe rotation and direction of rotation of a rubber roller 82, which isdriven from a shaft 83 by interconnecting gearing indicated in generalat 84. There is a shaft 83 for each of the computing heads, and it isprovided, in this case, on its outer end with a bevel gear, in dicated,in the case of the computing heads 57 and 58, at 85 and 86. The bevelgears merals and 91.

85 and 86 similar to the bevel gears for the master-wheel shafts, meshwith paired bevel gears loosely mounted on a shaft 87. These bevel gearsare indicated, in the case of the gear 85, by the numerals 88 and 89,and in the case of the bevel gear 86, by the nu- Clutches 92 and 93 areprovided between the pairs of gears to connect one or the other of thepaired gears in driving relation with the shaft 87. The shaft 87 is alsodriven from the motor 54 through the intermediary of a shaft 94, connected by a pair of bevel gears 95 and 96 at one end to the shaft 87,and by a pair of bevel gears 97 and 98 to the shaft 63 at the other end.

To shift the clutches for the master-wheel shaft and the tens-carryingshaft of each computing head, there is provided a composite shiftinglever, indicated in the case of the computing head 57, at 99, and in thecase of the computing head 58, at 100. These shifting levers areidentical and only one will be described. The composite shifting leverconsists of a main lever 101, pivoted at 102, and provided with a pin103 engaging in a groove in the master-wheel clutch 71 or 72. Pivotallymounted on a pin 104 provided on the main lever 101, there is pro videda supplementary lever 105, which has a movement relative to the mainlever 101, limited by a pair of fingers 106 and 107 engaging oppositesides of the pivot 102. This supplementary lever 105 is provided with apin 108, which engages in a circumferential groove provided in one ofthe tens-carrying clutches 92 or 93. The lost motion between the mainlever 101 and the supplementary lever 105 is provided, so as to permitthe settling of the. teeth in the different clutch faces. This lostmotion is taken up by a spring 109.

It will thus be composite levers seen that when one of the is shifted,the associated clutches will be shifted to concomitantly change thedrive of the master-wheel shaft and the assisting tens-carrying shaft,so that they will always rotate in corresponding directions either toadd or subtract, or they will not rotate at all in the case where it isdesired to have the associated computing heads silent.

Of course, these composite levers might be shifted directly manually. Inthis case, however, each of the main levers is provided with an eye 110,with which engage links 111 and 112 for the computing heads 57 and 58,respectively. The links 111 and 112 are connected, respectively, (Fig.4) to separate bell cranks 113 and 114, pivotally. mounted on a stubshaft 115, so that they may be rocked by these'bell cranks. The bellcranks are in turn rocked by links 116 and 117, which are drawn on bylevers 118 and 119, to which they are connected. These levers areprovided with hand-grips 120 and 121, to enable them to be manuallymanipulated, if desired, one of the hand-grips being bent over to permitmore ready access to the other hand-grip.

The levers 118 and 119 are pivot-ally mounted intermediate their ends ona stub shaft 122, so that they may be rocked by a pair of links 123 and124, which are con nected thereto at their lower ends. The links 123 and124 may in turn be drawn on by composite shifters 125 and 126,separately pivoted on a stub shaft 127. Each of the composite shiftersis provided with a centralizing element 128 and 129, respectively, whichin the case of the latter faces upwardly, and in the case of the formerfaces downwardly, to engage position-determining buttons 130 provided onopposite sides of a rotatable controller disk 131. Each centralizingelement 128 and 129 may be formed by providing a pair of flanges 132 and133 spaced apart from each other and provided with parallel reaches 134and 135 (Fig. 8),to form a channel therebetween, in which one of theposition-determining buttons 130 can pass to fix the location of theshifter 125 for any particular position of the disk 131. The flanges 132and 133 both flare outwardly from opposite sides of the parallel reaches134 and 135, so as to form guideways forcing the shifter to move to sucha position that the cooperating position-determining button 130 mayenter the channel formed between the parallel reaches. The reason forflaring the centralizing device in both directions is to permit theactuating movement of the disk 131 and a returning or ineffectivemovement of this disk.

The disk 131 forms a part of the controlling mechanism and is arrangedto be given a step by-step movement at the actuation of each of thetabulating keys 16 to bring the typewriter carriage into a new computingzone or column. For this purpose, the controller disk 131 is secured toan escapement wheel 136, which has secured thereto a gear 137 meshingwith a rack 138 on a bar 139. The bar 139 is guided for movement on aplate 140 and has connected thereto a spring 141, which is normallyunder a tension tending to drive the rack bar 139 and thus rotate thegear 137 with the escapement wheel 136 and the controller disk 131. Thismovement, however, is prevented'by a dog 142 which engages the teeth 149of the escapement wheel 136. The dog 142 is mounted on a bar or rail143, which is universal to all of the tabulating keys 16, with thepossible exception of the millions key, indicated at 144.

The universal bar 143 is supported by a pair of spaced arms 145, whichare mounted on a rock shaft 146, so as to form a universal frame. Thisframe is normally held in a raised posltion by one or more springs 147coiled about the shaft 146 and engaging under the arms 145.

lVhen the universal frame, including the universal bar 143, is in itsnormal raised position, the dog 142 will have the toe 148 thereof inengagement with one of the teeth 1490f the escapement wheel 136,preventing rotation thereof under the tension of the spring 141. Assoon, however, as one of the tabulating keys 16 is depressed, it willengagethe universal bar 143 and depress the same against the tension ofthe springs 147, thereby moving the toe of the dog 142 out of engagementwith the escapement wheel 136. Before, however, this wheel can completeits movement, a second pawl or dog 150, which is somewhat shorter thanthe dog 142, will be depressed to bring the toe 151 thereof into thepath of movement of the next tooth 149 on the escapement wheel 136,locking the escapement wheel and the controller disk 131 from furtherrotation.

When the tabulating key just depressed returns to its normal position,the universal bar 143 will likewise return, carrying both the dogs 142and 150 with it, thereby removing the dog 150 from engagement withthetooth 149 on the escapement wheel 136, and bringing the dog 142 intoengagement with this tooth, so that during one up-anddown movement of atabulating key, the dogs will alternate in action, permitting a singlestep movement of the escapement wheel 136 corresponding to thedistancebetween two of the teeth 149, and thus permitting a single stepmovement of the controller disk 131.

The dogs 142 and 150 are connected to a sleeve 152, which is common toboth of them, and which is further pivoted on the bar 143, so as toadmit of a swinging movement of the dogs relatively thereto. Thisswinging movement may be made use of in permitting a backward rotationof the escapement wheel 136, the teeth 149 thereof being inclined ontheir rear surfaces to cam the dogs aside.

In order to permit this movement of the dogs and yet maintain themnormally in cooperative relation with respect to the teeth 149, there isprovided a spring 153, which is secured to a lug 154 on the bar 143 andextends through an opening 155 in one of the dogs, 142. Inasmuch as thedogs are secured together by the common sleeve 152, the spring 153 willanswer for both of them. The inward motion of the dogs under the urgingof the spring 153 is limited by a stop 190.

After a single series of controlling ac tions of this controllingmechanism has been effected, as, for example, when a complete line ofnumbers has been written on the typewriter, then it. is necessary toretension the spring 141 and return the controller disk 131 to itsnormal position. For this purpose, the bar 139 may be provided with ahand-hold 156 at one end thereof, so that the operative can grasp thesame and return the bar 139 to its original starting position, and thusreenergize or retension the spring 141 connected thereto. Inasmuch asthe rack of the bar 139 still meshes with the gear 137, then this gearwill be rotated in a counter-direction, that is, in the oppositedirection to that shown by the arrows in Fig. 4, so that the escapementwheel 136 and the controller disk 131 will be returned to their originalstarting positions.

lVhile the controller disk 131 may be of any suitable form, the typeadopted in this instance consists in having a flat disk with a series ofperforations therein arranged in a circle. Every other perforation maybe used for the position-determining buttons 130 on one side of thedisk, and the intermediate perforations may be used for thepositon-determining buttons on the opposite side of the disk. That is tosay, with two computing heads, the alternate holes or perforationscorrespond to the controlling buttons on opposite sides of the disk andthus to the two shifters 125 and 126 and their accordant computingheads.

The position-determining buttons are shown in the form of screw-bolts,each provided with a head 157 (Figs. 9 and 10) and aneccentrically-located shank 158 of a size to conform to the holes orperforations in the disk 131. The shanks 158 are screwthreaded to enablethe attachment thereto of locking nuts 159, which secure thepositiondetermining buttons in any adjusted position. The adjustment ofthe buttons and the locking of them in position may be aided by ascrew-driver slot 160 provided in each head 157.

The position-determining buttons 130 are to be located on the disk 131in one of three positions corresponding to adding, neutral andsubtracting. By reference to Fig. 9, these three positions will be notedfor the top side of the disk. 161 indicates a position-determiningbutton in its adding adjustment, that is, with the head 157 thereofswung to its position farthest from the center of the disk 131; 162indicates a position-determining button in its subtracting position withthe head 157 swung to its position nearest the center of the disk 131;and 163 indicates the adjustment of the positiondetermining button to alocation corresponding to a neutral condition of the computing head,that is to say, with the head 157 thereof located in a position midwaybetween its extreme outer and inner possible locations. Of course it isto be understood that the heads 157 of the position-determining buttonsare considerably larger and deeper than the nuts 159 which hold them inposi-' tion, so that the centralizing element 128 I state of thecomputing heads manually independent of the automatic controllingmechanism, as in case it is desired to correct an error. In such anevent, the manual levers 118 and 119 may be manipulated in such a manneras to leave the automatic controlling mechanism in the same condition.For this purpose, the shifters 125 and 126 are composite, that is tosay, formed of two parts having a relative movement when neoessary. Inother words, each composite shifter includes a bell crank lever 164:, toone arm 165 of which is secured the centralizing element 128 or 129. Theother arm 166 of the bell crank lever has a mate in an arm 167, which ispivoted to the same stub shaft 127 in close juxtaposition thereto. Thearm 167 is normally connected to the arm 166, so that the two will movetogether as a unit by a latch 168, which is held in its locking positionby a spring 169. The arm 167 has a perforation 170 in which the link 123or 124C is hooked to form the connection to the corresponding lever 118or 119.

The latch 168 is pivoted to an extension 171 on the arm 167, and isprovided with a beveled locking tooth 172, which engages a correspondingsocket 173 in the arm 166.

This yielding connection between the two parts of the shifting leverpermits the forcible disengagement of the latch 168 and thus of the arm167 from the arm 166 when the associated lever 118 or 119 is manipulatedto vary the state of the associated computing head from that determinedby the particular positionii'ig button 130 in engagement with thecentralizing element 128 or 129. In other words, by this forcibledisengagement, the character of computation can be controlled manuallyindependent of the automatic controlling means.

In addition to the fact that the latch 168 may be'readily cammed out ofits socket while the bell crank lever 164: of the shifter is heldstationary by engagement with one of the buttons 130, this latch mayalso be forced into position'when the corresponding lever 118, 119, isreturned to a position cor responding to the position of the bell cranklever 164. For this purpose, the arm 166 of the lever 164;, which isspread out at the point of engagement with the latch 168, is beveled atboth sides of the notch 173, as at 17 1 and 175, to admit of the cammingby of the latch on a re-mating relative movement of the arms 166 and167. The limits of movement of the shifter may be determined by stops176. V 7

It might happen that the operative after completing a line of writingand running through the line of computing zones, would forget to returnthe rack bar 139 at the same time that the typewriter carriage isreturned to its starting position for a new line. A

lock is therefore provided to guard against with a series ofperforations 177 arranged at intervals corresponding to the stepmovements of the escapement wheel and of'the controller disk 131, andpreferably in register with the teeth 1 19 of the escapement wheel 136.These perforations may be numbered from 0 to 10 to correspond to theinitial position of the typewriter carriage and the several possiblecomputing zones thereof. The alternate perforations for thepositioning-determining buttons on the controller disk 131 may becorrespondingly numbered, so that the stopping points of this disk willaccord with the different columns or zones as typewritten. A look 178may be secured, by means of a bolt 179, at any one of these points bypassing the bolt throu h one of these openings 177. The lock 178projects beyond the root circle of the escapement wheel, and, in fact,conforms at its outer end to the particular tooth with which it isbrought into register, on one side thereof, that is, on the inclined orback side thereof. This lock, however,projects beyond the locking sideof the tooth with which it is cooperating, so as to prevent the dog 142from being depressed out of the path of this particular "tooth.

It will be seen that after the controller has been moved step by step tothe end of the desired controlling sphere thereof, then the dog 1 12will be located directly above the guard or look 178, preventing afurther actuation of any of the tabulating keys 16. In this instance,the guard is shown as being located at the fourth station correspondingto four computing zones or columns, beyond which the carriage cannot betabulated. and the computing mechanism controlled in its state until theautomatic controlling mechanism has been returned to its initialposition.

In preparing the machine for operation, the position-determining buttons130 are properly located on the disk 131 for the sequence of computingactions desired of the computing heads. In this instance, the top sideof the disk 131 controls the upper computing head and the bottom side ofthe disk 131 controls the lower computing head, there being but twoheads shown. If it is desired to add in any particular zone, the buttonwill be located in the position illustrated in Fig. 9, at 161. If it isdesired to have the computing head silent in any zone a button in aposition such as that indicated at 163, will be used. If, on the otherhand, it is desired to subt act in any computing Zone, the positioningbutton will be adjusted to a location shown at 162.

Vhen the buttons for the successive steps or stopping points of thecontrolling mechanism have been properly adjusted, it may be determinedhow far the computing mechanism is desired to be used. That is to say,if, as illustrated in the drawings, it is desired to have four computingzones or columns, there will be placed on the rack 20 of the carriage,four of the carriage stops 19, as illustrated in Fig. 3, so that thecarriage will be positioned by an actuation of the tabulating keys forfour different columns or zones. The guard or lock 178 can then bepositioned on the escapement wheel 136 at the number 41 positioncorresponding to the termination of the fourth. step movement of thiscontrolling mechanism. That is to say, the 0 position corresponds to theinitial position of the carriage; the 1 position corresponds to thefirst computing zone; the 2 position to the second computing zone, andso on. Thecontrolling mechanism is ar anged 'ith the spring 11-1completely tensioned and the tooth 1&9 of the escapement wheel 136 inregister with the O position in engagement with the dog 14:2. Thecarriage is likewise positioned to its extreme location at. the right.The tabulating key 16 is then struck to bring the carriage to the firstcomputing zone or column. This actuation of the tabulating key will notonly determine the position of the carriage but will depress theuniversal bar 1&3 and bring the dog 142 out of engagement with theinitial toot-h. 1&9 (at 0 Zone), concomitantly bringing the short dog150 intothe path of the next tooth.

hen the tabulating key returns, the springs 127 will likewise return theuniversal frame including the universal bar 143, so that the dog 150 isremoved from engagement with the tooth on the escapement wheel 136, andthis escapement wheel with the controller disk 131 flies around underthe propulsion of the spring 141 until this next tooth which has justescaped past the dog 150, comes into engagement with the dog 142 whichby this time has risen into the path of this tooth.

During this movement, the positioning buttons on the top and bottom ofthe controller disk 131 will engagethe bottom and top of thecentralizing elements 128 and 129, and adjust them to positionscorresponding to the positions of the heads of these buttons. Thismovement will be transmitted to the clutch-shifting composite levers 99and 100, so that the drive and character of drive of the master-wheelshafts and the tensarrying shafts of the computing heads will bedetermined, and thus the state or character of computation carried on bythese computing heads determined.

After the digits of a number to be computed in this first computing Zoneor column have been written on the work-sheet on the carriage and run upin the computing heads, then the tabulating mechanism will be againactuated to bring the carriage to the next computing zone or column,which actuation will likewise cause a step movement of the controller orcontrolling mechanism, to provide a readjustment of the states of thecomputing heads, if it should so happen that it is desired to changethem for the next column. Of course, the positioning buttons in twosuccessive columns might be the same for any one computing head or forboth computing heads, so that the mechanism would remain in its state ofprevious adjustment. This action is repeated for each computing zone orcolumn until the fourth computing Zone or column in the example given,is finished. Then it will be impossible to actuate the tabulatingmechanism as the dog 142 will engage the guard or look 178 and beprohibited from any downward movement. This, then, shows that the end ofthe sphere of control of the controlling mechanism has been reached forthe particular adjustment thereof, and that it is necessary for theoperative to return the controlling mechanism to its original positionand retension the spring 1 17 by actuating the hand-hold 156. This,then, while admitting of the automatic control of the states of aplurality of computing heads for the different zones of columns,prevents an overrunning of this mechanism, and further prevents statesbecoming discordant with the particular zones of the typewriter carriagewith which the successive step movements are intended to accord.

If itshould be desired to manipulate the composite state-controllinglevers for any computing head, so as to obtain a state other thandetermined by the automatic mechanism, as in case itis necessary to makea correction, then the particular lever 118, 119, corresponding to thecomputing head which it is desired to control, is manipulated, which maybe done without a disruption of the mechanism or an interference withthe automatic mechanism by virtue of the composite character of theshifters 125, 126.

In case it should be required to actuate the typewriting mechanism tospace the carriage without operating the state-controlling mechanism,the millions key could be used, inasmuch as it does not project abovethe universal bar 143.

It will thus be seen that there is provided an automatic controller orcontrolhng mechanism for determining the state of a plurality ofcomputing heads according to a determined plan.
